Disagreeing

I'm afraid that's not accept able to us. I'm afraid we can't agree with you there. Can I just pick you up on a point you made earlier. I understand where you're coming from / your position, but…We're prepared to compromise, but…If you look at it from our point of view,… As we see it…That's not exactly as we see it. Is that your best offer?

Clarifying

Does anything I have suggested / proposed seem unclear to you? I'd like to clarify our position. What do you mean exactly when you say….Could you clarify your last point for me?
